Ricoh to buy Pentax camera business from Hoya

I've been so busy that I missed this news completely.
But on reflection, I honestly believe this is a positive move for both Hoya and Ricoh. Hoya was the white knight who came at the right time to bump off the ultra-conservative and frankly clueless old Pentax management and saved the company financially. For this I am grateful to them. Their innovative approach helped them roll out new models that brought Pentax back on track, regaining new users and stopping the declining market share. But in the larger scheme of things, Hoya with its long history as a maker of optical glass nevertheless never had a tradition of making cameras nor was involved in photo imaging per se. Now that they have rejuvenated the Pentax brand, it makes financial sense to reap a financial gain by selling it to a company with a proven history in imaging, which Ricoh definitely has.

For Ricoh, the acquisition of Pentax is definitely a boost for them. For one, they would gain the bigger brand recognition that they have never managed to have all this years. It also makes sense to retain the Pentax name sp as to not kill the golden goose now that the Pentax user base has grown over the last few years. The challenge for Ricoh is to channel their energies that have allowed them to come up with unique (so would say quirky) line-up of cameras to become a full fledged mainstream brand that will occupy the mind share of the camera buying public. Overnight they've become a DSLR player and their experience in compact cameras will no doubt filter into future Pentax compact cameras. So I see this news as positive. On a personal note, my first camera was a Ricoh 500GX rangefinder and I still have fond memories of the fine images I had from that 40mm Rikenon lens. The other good thing is my sis-in-law currently works in Ricoh...

Manual/Takumar/M42 Screwmount lenses on Pentax DSLRs

I've written two articles on how to use Manual K-mount M & K series / Takumar / M42 Screwmount lenses on Pentax DSLRs, as well as how to meter.

How to use Screwmount/Takumar lenses on Pentax DSLRs (K-7, K-x, etc.)

Manual Metering on Pentax DSLRs with Manual and Automatic Lenses

There is now also a tutorial video:

You Tube

In a nutshell:

First, if your camera won't fire, set "Allow aperture setting other than A" to 2 (allowed) in the custom function menu. Then:
  1. Set your camera to M mode using the mode dial (your camera won't fire in other modes*)

  2. Compose and focus your image.

  3. Using the aperture ring (the ring at the very back of your lens; it will have numbers such as 2.8, 4, 5.6, 8 written on it), select your desired aperture setting. Note that the smaller the aperture number is, the more light passes through the lens, and the blurrier the out of focus areas of your photograph will be.

  4. [Screwmount lenses only] Switch the diaphragm clutch on your lens to "Manual" (you can leave it on Auto when composing and focusing).

  5. Measure the light by either pressing the "Green Button", or pushing your power button to DOF preview mode (only available on select bodies). Your camera will automatically set the shutter speed for you.

All that's left now is for you to press the shutter release button to take your photo. Congratulations- you've now learned how to use M42 and M & K manual lenses with Pentax DSLRs!

*Screwmount lenses may also be used in Av mode since they are always stopped down to the aperture you will be shooting at (unlike M&K lenses, which are stopped down only when the shutter is released or when you meter as described above).

Need a M42 adapter? Pentax's adapter allows your lenses to focus to infinity and is readily available:

You may also find our older discussion thread on this topic very helpful:
An occasional issue with late Takumar lenses: Why is the Auto/Man diaphragm clutch stuck on my S-M-C Takumar lens?

If your manual focus lens has an "A" setting on the aperture ring, leave it in "A" and instead use the e-dials on your camera to control the shutter speed and aperture. Don't follow the steps above.

Sticky: The Usage of Green Button

The following are copy from several different user's post.
Hopefully this can help more newcomers (or not) to know more about the great Green Button.
Thanks to Peter Zack, RuiC, sezme.

In manual mode (A,FA, DA etc series lens) you can push the button and it sets the exposure for the program mode and the program line. Program line is the setting you have selected in the camera menus, like MTF (where the camera sets the lens at the best aperture for that lens, which is programmed into the lens by the manufacturer). Then you can fine tune the exposure to your liking from this setting. Very old school but an absolute requirement for a serious shooter in tough lighting and many other situations. (Peter Zack)

Step Down Metering
With an M or M42 lens, you can use the button to stop the lens down and take a meter reading. For those that own these lenses, it's an approximate reading and you have to understand (with practice) the way your particular lens will meter on the attached body. In most cases, these lenses meter well wide open but tend to over expose in middle apertures. So you use the green setting recommendations as a starting place to adjust to the correct exposure. (Peter Zack)

Return to HyperProgram(P) after changes
In HyperProgram (P) mode you can turn the front e-dial to adjust exposure time other than P suggests and it changes to Tv mode. If you turn the rear e-dial it becomes Av mode. Then press Green-button it returns to P mode again. (RuiC)
image from Digiichi - Next generation hyperprogram.

From Full Manual mode to P, Av or Tv
The green button in M mode get you to P, Av or Tv dependant on what mode is chosen in the green button menu set up. (excellent if you want to use it like an on-demand spot-meter)

The green button doesn't change from M (manual) mode to any other mode - it leaves you in M mode. It just momentarily gives you the effect of being in one of those other modes (which one depends on how you've set it up in your custom options) - setting the same aperture and/or shutter speed that you'd get it you were in one of those other modes, but then leaving that set. As opposed to constantly readjusting as the light changes.

(thanks lol101, Marc Sabatella, adwb)

Act as Reset button: Reset Exposure Compensation, Flash Compensation
If you have set exposure compensation, hold the exposure compensation button plus the green button will reset the meter to zero E.C.
* You can also reset the Flash Compensation with green button. (thanks rockmaster1964)

Fast access to set Auto ISO
if you press the ISO button (OK button on K10/20) plus the green button, it sets ISO to auto. A very useful button!
Also in Av/Tv if ISO is made accessible via one of the control dial, green button switches to auto-ISO. (thanks lol101)

Zoom in in Playback mode
In playback, after you zoom, Green button zooms IN and EV+- zooms OUT

Cold wind and some rain yesterday created this in my garden. During 30 minutes of sunshine today I could take a few shots.

Meanwhile it is -10C again ...
